20Z20BD.1 50.8 mm Dia. Zerodur Broadband Dielectric Mirror; t=12.7mm 488-694nm

This is the 20Z20BD.1, a 50.8 mm diameter Zerodur broadband dielectric mirror with a thickness of 12.7mm, specifically designed for the wavelength range of 488-694nm. The mirror is sourced from the reputable vendor MKS/Newport, and detailed information about the product, including its availability and pricing, can be found on their official website at https://www.newport.com/p/20Z20BD.1.

The mirror is a circular dielectric type, which is renowned for its high reflectivity and durability. Its thin-lens shape allows for efficient integration into various optical systems. The coating on the front surface is the new BD.1 AOI 0, ensuring optimal performance and longevity.

The mirror's material, Zerodur from Schott, is a low-thermal-expansion glass-ceramic that guarantees excellent dimensional stability and high resistance to temperature changes. This makes the 20Z20BD.1 an ideal choice for applications requiring precise optical alignment and stability.
